The lighting system of the banquet hall should give priority to the dimming system; The lobby of the banquet hall (where guests sign in, etc.) should be equipped with weak current interface and strong current socket for wall-mounted TV; If it is a large banquet hall, it should be separated by movable partitions, which requires that the sockets on the wall of the banquet hall should be evenly distributed in each separation area; The banquet hall may require a temporary stage for performance, so it is suggested to provide 2 channels of 111A power supply as temporary power supply for the stage.
